The Chhatrapati Shivaji International Airport's Terminal 2 was evacuated in what was termed for apparent security reasons. The reason for the drill is undisclosed as of yet.

A member of an airline, who wished to remain anonymous stated the airport was closed due to a mock drill rehearsal that was being carried out.

Passengers were inconvenienced by the massive flight delays and those who boarded were required to undergo security checks again.

In March this year, a similar mock drill was conducted at the Chhatrapati Shivaji International Airport (CSIA), which ended in failure. It exposed loopholes in the emergency response system, with the preliminary report mentioning that eight of the total 170 (dummy) passengers died during the drill.
